Can you please help me illustrate a sequence diagram for my Thermostat Device object from my OOA class exercise.

My class exercise is below*

Smithmethod& Co. is an advanced water heater controller that connects to the thermostat of a water heater and deliver more effictive control of the water temperature to save money and guard the environment . Smithmethod & CO. sets the water heater thermostats high when hot water is much in need, and sets it low when there is not much water needed. For example, Smithmethod & Co. can be told to set the thermoset high on weekday mornings and evenings and all day on weekends and low during the middle of weekdays and at night.

Furthermore, Smithmethod & Co. can be told to set the thermostat high all the time in case of illness or other need, or be told to set the thermostat low all the time in case of vacation or some other extend absence from the house.

The homeowner can specify values for the following parameters:

Low Temp temperature when little or no hot water is needed.

High Termp Termperature when much hot water is neede

Weekend Days Days when the thermostat will be set to High Temp all day long; on all other days it will vary between Low temp and High Temp.

Peak Times From one to three time periods on a 24-hour clock during which the thermostat will be set to High Temp on non-weekend days. On Weekend Days, the thermostat will be set to High temp during the duration period between the earliest time and the latest time set in the Peak Times.

Mode-

Stay Low Mode- Thermostat is set ot Low temp.

Stay High Mode- Thermostat is set to High temp.

Normal Mode- Thermostat is changed between Low Temp and High temp on a regular schedule, as explained above.

Smitmethod&Co. has its own internal clock that it checks every second to determine how to set the water heater thermostat.

**In software engineering, a system sequence diagram (SSD) is asequence diagram that shows, for a particular scenario of a use case, the events that external actors generate, their order, and possible inter-system events.
